All sponsors are reminded that new rules across the sponsorship system are being introduced in two stages in April 2011. Changes relating to tiers 2 and 5 take place on 5 April and changes in relation to tier 4 come into effect on 21 April. Sponsors must ensure that they are fully aware of the changes, some of which fundamentally affect the concept of sponsorship. Penningtons' immigration team is running a series of seminars (details below) and we also offer on-site bespoke training sessions.
